memory metal

Students learn about a class of materials called shape memory alloys. They will explore how these materials work and what applications these materials are used in. They will discuss phase transformations.

To encourage students to compare and contrast science and technology; experimental design and industrial design; and physics and its impact on nanotechnology. The students will be able to analyze and reflect on the forces, motion and energy transformations that can be shown by a Rube Goldberg Device and to experience the impact that Nitinol wire has on the device.

"Exploring Materials - Memory Metal" is a hands on activity in which visitors compare the properties of a memory metal spring to an ordinary spring. They learn that the way a material behaves on the macroscale is affected by its structure on the nanoscale.
